BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.

ATOMIZER.

Application filed June 20, 1924. Serial No. 721,284.

This invention relates to ato-mizers and more especially to the discharge pipe and sprayer for the liquid that is to be broken up into fine drops and forced into the atmosphere and the object of the invention is to provide a piston and rod that may be operated by the finger to draw liquid from a container and force it through the said discharge pipe that is flattened from its original tubular shape so that while the, central portions of the flattened tube are in contact and impassable there remains a. passage for the liquid at each side and near its upper end the flattened tube is given several helical turns while its extremity is formed into a head having a minute perforation.

A further object of the invention is to thus give the broken up liquid a gyratory movement within the sprayer-head and as it leaves the sprayer it is thoroughly atomized.

These and other objects and details of the invention are more fully described in the following specification, set forth in the appended claims and illustrated in the accompanying drawings, wherein:

Fig. 1 is a side elevation of the improved atomizer.

Fig. 2 is an enlarged vertical sectional View through the same.

Fig. 3 is a longitudinal sectional view through the sprayer head.

Fig. l is a cross sectional view through the flattened tube.

Fig. 5 is a cross sectional view through the tube above the container cap.

In the production of small portable pumps for atomizer-s to be used in connection with .containers it has been the practice to locate the sprayer head at the end of a movable tube that comprises the piston red, the operating rod and the discharge pipe.- These several uses of this pipe, however, have been found undesirable because of the difficulty of locating the spray at a desired location on account of the repeated reciprocation of the sprayer head.

The atomizer as used in these sprayers is generally formed of a block or hub having peripheral inclined grooves to give a whirling movement to the liquid and is inclosed by a perforated cap. A serious objection to this latter form of sprayer is its cost and its many parts.

The present invention is designed to have the sprayer remain stationary while the ato'mizing is being performed and to simplify the sprayer so that it may be produced at av minimum cost. With these objects in view the atomizer comprises a pump cylinder 10 having a perforated cap 11 through which moves the piston rod 12 that has at its upper end the eye 13 in which the finger of the operator may be inserted to reciprocate the rod 12. p

Within the cap 11 is a b01914: that carries a packing 15 of suitable fabric to absorb and maintain moisture, for a considerable length of time.

At the lower end of the rod 12 is the piston made up of packing cups 16 and intermediate moisture absorbing washers 17 contained in a. shell 18 that is perforated to allow the moisture to attack the packings 16, and at the lower end of the cylinder is an inlet valve 19 that allows the liquid to enter the cylinder and arrests its egress.

Above the valve 19 is a diaphragm 20 to prevent its dislocation and at one side of the valve seat 21 is an outlet pipe 22 having at its upper end a valve seat 23 for the check valve 24 and attached to said upper end is the atomizer tube 25.

This tube 25 was originally cylindrical as it so remains at the point of attachment to allow play to the ball 2& but practically the balance of the tube is compressed and flattened, as shown by the cross section Fig. 4, where it will be seen that while the two opposite sides are brought together there remains at the ends of said sides the passages 26 for the expelled liquid to move through to reach the atomizer head. At 2'? where the flattened tube passes through the cap 28, for the mouth of the bottle or container the tube retains its original width to prevent twisting movementin the cap. and above this point the tube is given a spiral twist if?) and terminals in the head 30 having the minute perforation 31.

It will be seen that the area of the perforation 31 is smaller than the cross sectional area of the passages 26. e

As the piston is reciprocated the liquid is drawn up a tube 82 and forced up the tube 25 in two streams each given a gyratory movement by the spiral formation 29 within the head 30 and finally discharged as a cloud through the perforation 31.

It is obvious that the parts may be otherwise arranged or modified without departill) ing from the essential features above described or from the scope of the appended claims.

\Vhat I claim as new is: p

1. A sprayer comprising a tube flattened to bring opposite walls into contacting relation throughout a region extending longitudinally and medially of the tube, the contacting relation terminating short of the respective ends of the tube, whereby to provide separate passages leading from a common inlet to a common discharge chamber, said tube being twisted spirally immediately in advance of said discharge chamber.

2. A sprayer comprising a tube flattened so as to bring the opposite Walls into contacting Water tight relation throughout a region extending longitudinally and medially of the tube, the contacting relation terminating short of the respective ends of the tube whereby to provide separate passages leading from a common inlet to a chamber at the end of the tube, said flattened tube being twisted spirally immediately in advance of the cl1a mb'er and the passage entering said chamber at opposite sides to give the liquid leaving said passages a whirling movement.

3. A sprayer comprising a tube flattened so as to bring opposite Walls into contacting Water tight relation throughout a region extending longitudinally and medially o't the-tube, the contacting relation terminating short of the respective ends of the tube whereby to provide separate passages lea ling from a common inlet to a chamber formed at the end of the tube, and meam whereby the passages discharge liquid at opposite sides with a whirling movement.

In testimony whereof I hereunto afllx my signature.

JACOB STIRISS.
